COMMUNICATION INTERFACE MODULE (CIM)
VERSION 3.0
1. Introduction
This section is intended version 3.0 of the Communication Interface Module (CIM). For
other product versions, contact Thomson Technology, Inc. to obtain applicable
instruction manuals.
The Thomson Technology (TTI) remote communication system with the CIM 3.0 and
Modbus™ protocol provides remote monitoring and control of TTI microprocessor-based
controllers as used in the power generation industry. The system consists of 2 main
components as follows:
•
Communication Interface Module (CIM): The CIM provides the hardware and
software interface between a Modbus compliant device (customer supplied) and the
specific microprocessor-based controllers as used at a generator site.
•
Remote Terminal Unit (RTU): An RTU is a device that directly operates the
equipment at a generator site. These devices are the actual microprocessor-based
controllers as developed by Thomson Technology, Inc. (e.g. MEC 20 engine
controller or TSC 800 transfer switch controller.
The following diagram depicts a typical remote communication system.
